Jericho, through participation in the STACK JV, strategically participated in the drilling & completion of the two primary stacked formations present in the Anadarko STACK Play: the Meramec Shale and Lower Osage. The Wardroom Well (Meramec), on the STACK JV’s western flank, has had positive results and continues to perform in line with its proposed type curve, with the most recent 60-day average production at 405 BOEPD. The Swordspear Well (Lower Osage), on the STACK JV’s northeastern flank, was drilled to 12,528 total measured depth and was successfully fracture stimulated. The well is currently in flow-back with less than 10% of the fluids re-captured. Lower Osage wells, as noted by Alta Mesa at the April 2018 IPAA Oil & Gas Symposium (Pg11AltaMesa), commonly takes 60-100 days from the start of flow-back to reach peak initial production.

With the success, so far, of its initial two well STACK program, the STACK JV has continued to aggressively acquire acreage in the Northern STACK contiguous to its core positions. Thus far, in 2018, the STACK JV has acquired 7,366 additional net acres bringing Jericho’s total STACK JV position to ~16,000 net acres. Jericho’s entry cost and subsequent leasing efforts continue to be extremely attractive compared to recent public market acquisitions and valuations.

Brian Williamson, CEO of Jericho Oil, stated, “We are very pleased with our development efforts and continued acreage acquisitions so far in 2018. With a successful test of the Meramec and encouraging results thus far on our Osage test in the STACK, the delineation of our nearly 16,000 acres in the play continues to be our focus in 2018. We look forward to updating our shareholders on our Swordspear well in addition to fostering a continued collaboration in the northern STACK with public and private offset operators to shine a light on the prolific 400-foot-thick Osage formation prevalent throughout our Major County acreage position.”
